Modified phytases

ABSTRACT

A process for the production of a modified phytase with a desired property improved over the property of the corresponding unmodified phytase is disclosed, as well as modified phytases, polynucleotides encoding modified phytases, and animal feed including modified phytases.

BACKGROUND OF THE INVENTION

Phytases (myo-inositol hexakisphosphate phosphohydrolases; EC 3.1.3.8) are enzymes that hydrolyze phytate (myo-inositol hexakisphosphate) to myo-inositol and inorganic phosphate and are known to be valuable feed additives.

A phytase was first described in rice bran in 1907 [Suzuki et al., Bull. Coll. Agr. Tokio Imp. Univ. 7, 495 (1907)] and phytases from Aspergillus species in 1911 [Dox and Golden, J. Biol. Chem. 10, 183-186 (1911)]. Phytases have also been found in wheat bran, plant seeds, animal intestines and in microorganisms [Howsen and Davis, Enzyme Microb. Technol. 5, 377-382 (1983), Lambrechts et al., Biotech. Lett. 14, 61-66 (1992), Shieh and Ware, Appl. Microbiol. 16, 1348-1351 (1968)].

The cloning and expression of the phytase from Aspergillus niger (ficuum) has been described by Van Hartingsveldt et al., in Gene, 127, 87-94 (1993) and in European Patent Application, Publication No. (EP) 420 358 and from Aspergillus niger var. awamori by Piddington et al., in Gene 133, 55-62 (1993).

Cloning, expression and purification of phytases with improved properties have been disclosed in EP 684 313. However, since there is a still ongoing need for further improved phytases, especially with respect to the activity properties, it is an object of the present invention to provide such improvements.

SUMMARY OF THE INVENTION

Accordingly, this invention is directed to a process for the production of a modified phytase with a desired property improved over the property of the corresponding unmodified phytase which comprises:

(a)determining the three dimensional structure of the unmodified phytase and of a second phytase which has the desired property by aligning the amino acid sequences of said phytases with the amino acid sequence of a third phytase which is the phytase of Aspergillus niger and using the three dimensional structure of the phytase of Aspergillus niger as a template based on the alignment to determine said three dimensional structures;

(b)determining from the structures of step (a) the amino acids of the active sites of the unmodified phytase and of the second phytase having the desired property which active site provides the desired property and comparing the amino acids which form the active sites to identify which amino acids are different in the active site of the second phytase from the amino acids in the active site of the unmodified phytase;

(c)constructing a DNA sequence coding for the modified phytase by obtaining the DNA sequence of the unmodified phytase and changing the nucleotides coding for the active site which provides the desired property for said unmodified phytase so that at least one of the amino acids in the active site which provides the desired property is substituted by one of the amino acids which was identified as being different in step (b);

(d)integrating such a DNA sequence into a vector capable of expression in a suitable host cell; and

(e)transforming the suitable host cell by the DNA sequence of step (c) or the vector of step (d), growing said host cell under suitable growth conditions and isolating the modified phytase from the host cell or the culture medium.

Either or both of the unmodified phytase and the phytase with the desired property may be of eukaryotic origin, especially of fungal origin. Such phytases are preferably of Aspergillus origin, for example phytase from Aspergillus fumigatus. In a preferred process, the phytase with the desired property is a phytase from Aspergillus terreus. In another preferred process, the unmodified phytase is a phytase of Aspergillus fumigatus and the phytase with the desired property is the Aspergillus niger phytase. In yet another preferred process, the unmodified phytase is a phytase of Aspergillus fumigatus and the phytase with the desired property is the Aspergillus terreus phytase.

Also part of this invention is a modified phytase with a specific activity improved over the specific activity of the corresponding unmodified phytase (for example Aspergillus fumigatus) wherein the amino acid sequence of the corresponding unmodified phytase has been changed by one or more of deletion, substitution and addition by one or more amino acids to obtain the amino acid sequence of the modified phytase. A preferred phytase has an amino acid sequence homologous to that of the phytase of Aspergillus niger (SEQ ID NO. 1 and has an amino acid sequence that has been changed in at least one amino acid position selected from the following amino acid positions which correspond to positions of the amino acid sequence of the phytase of Aspergillus niger: 27, 66, 71, 103, 140, 141, 188, 205, 234, 235, 238, 274, 277, 282, 340 and 424, in particular wherein the amino acid position is selected from 27, 66, 140, 205, 274, 277, 282, and 340.

A preferred modified phytase has an amino acid sequence which has been changed at position 27 alone or in addition to other of the above positions, in particular at least at position 66 and/or position 140. Thus preferred phytases are modified at position 27 and 66 or 27 and 140.

For any such phytase, the amino acid at position 27 may be replaced by a specific amino acid selected from one of the following groups:

a) Ala, Val, Leu, Ile; or b)Thr; or c) Asn.

Particular modified phytases of this invention are characterized by at least one of the following changes in amino acids at positions: Q27L, Q27N, Q27T, Q27I, Q27V, Q27A, Q27G, S66D, S140Y, D141G, A205E, Q274L, G277D, G277K, Y282H and/or N340S.

Also part of this invention are polynucleotides comprising a DNA sequence coding for the modified phytases produced by the above method. Polynucleotides comprising DNA sequences coding for the phytases described above which are modified at particular amino acid positions are included.

Also included are vectors, especially expression vectors, which contain the polynucleotides of this invention, and host cells which contain these polynucleotides directly or within a vector.

Another aspect of this invention is a food or feed composition which contains modified phytases described above.

DETAILED DESCRIPTION OF THE INVENTION

The process of this invention allows the production of a modified phytase with improved activity by using structural information about phytases to design the improvement. First, the three dimensional structure of the phytase to be modified and, optionally of another phytase with activity properties which are more favorable than the ones of the phytase to be modified is/are computer modelled on the basis of the three dimensional structure of the phytase of Aspergillus niger (ficuum). Then, the structure of the active sites of the phytase to be modified and of the phytase with the more favorable activity properties are compared and those amino acid residues in both active sites which are different are identified, after which a DNA sequence coding for a modified phytase is constructed by changing the nucleotides coding for at least one of the amino acids by which both active sites differ. The modified phytase is then obtained by integrating such a DNA sequence into a vector capable of expression in a suitable host cell, transforming a suitable host cell by the DNA sequence or the vector, growing the host cell under suitable growth conditions and isolating the modified phytase from the host cell or the culture medium by methods known in the state of the art.

As stated above, this process is particularly useful where the phytase to be modified is of eukaryotic, preferably fungal, more preferably Aspergillus, e.g. Aspergillus fumigatus origin and the phytase with more favorable activity properties is of eukaryotic, preferably fungal, more preferably Aspergillus, e.g. Aspergillus niger or Aspergillus terreus (Aspergillus terreus cbs 116.46 or 9A1) origin, or the phytase to be modified is a phytase of Aspergillus fumigatus and the phytase with the more favorable activity properties is the Aspergillus terre us phytase or the phytase of Aspergillus niger.

Thus, the unmodified phytase (for example a wild-type phytase) which has a property to be improved, and the phytase which has that property in an improved version (i.e. the desired property which the modified phytase will be designed to possess) may be derived from any known source of phytases. Various plants and microorganisms are known to produce phytases [e.g. reviewed in Wodzinski, R. J. and Ullah, H. J., Advances in Applied Microbiology 42, 263 (1996)]. Thus any enzyme which may be isolated by conventional methods and determined to be a phytase by standard assays (see e.g. EP 420 358) is a suitable phytase for this invention. Sequence and structure information for such phytases may be obtained by conventional techniques or from publicly available databases.

Preferred phytases are those isolated from fungi such as Aspergillus species [Shieh, T. R. and Ware, J. H. Appl. Microbiology 16, 1348 (1968); Yamada et al., Agr. Biol. Chem. 32, 1275 (1968);Van Hartingsveldt et al., in Gene, 127, 87-94 (1993), European Patent Application, Publication No. (EP) 420 358, Piddington et al., in Gene 133, 55-62 (1993); Wodzinski, R. J. and Ullah, H. J. (s.a.) and Mitchell et al., Microbiology 143, 245 (1997)]. Aspergillus are well known fungi commonly isolated from natural sources by conventional methods. In addition, Aspergillus species may be obtained from depositories.

Once such a fungus is obtained, DNA expressing its phytase can be isolated by conventional methods [see Mitchell et al., Microbiology 143:245 (1997) Van Hartingsweldt et al. (s.a.); Dox and Golden (s.a.); EP 420 358; Piddington et al (s.a.) and WO 94/03612] (for example cloned, expressed, and assayed by phytase activity assays to obtain a clone expressing the phytase) for use in this invention. Specifically, the phytase DNA can be used to isolat the phytase, whose amino acid sequence and three-dimensional structures can also be obtained by known methods, such as crystallography or computer modelling. Alternatively, the phytase may be isolated by conventional methods for isolating proteins such as enzymes, and analyzed as described. Also, DNA and amino acid sequences may be obtained from publicly available databases.

Although other three-dimensional phytase structures may be obtained and used, it is preferred to use the three-dimensional of the Aspergillus niger phytase in the process of this invention (see Kostrewa et al., Nature Structural Biology 4:185 (1997) or of Aspergillus fumigatus. A useful strain of Aspergillus niger may be obtained from the American Type Culture Collection [address] under accession number ATCC 9142. Like any three-dimensional phytase structure useful in this invention, the three-dimensional structure of the A. niger phytase is obtained by techniques known to a skilled practitioner. Based on an amino acid sequence such as the A. niger amino acid sequence provided herein, (SEQ ID NO:1) computer programs can provide theoretical structures. Crystal structures can also be obtained, as in Example 1 below. From these three-dimensional structures, active sites can be defined, such as the part of the phytase which interacts with substrate. This active site can then be localized to the segment or segments of the amino acid sequence which together form the active site, which segment or segments can then be modified, the whole sequence expressed as a modified phytase which is then tested to see if the activity has been improved. By this means a desired property can be designed into an unmodified phytase, using the three dimensional structure of the A. niger phytase as a template based on the alignment.

Specifically, the structure of A. niger is analyzed to find out which amino acid residues form the active site which determines specific activity. Then, the amino acid sequence of an unmodified phytase with a given specific activity and that of a phytase which has a desired property, e.g. a higher specific activity, are aligned homologous (as defined below) to that of A. niger to provide a best fit, and the amino acid residues which correspond to the A. niger active site in the other phytases are determined and compared, to identify which amino acids are different in the active site of the phytase with the desired property. The active site amino acid residues of the unmodified phytase may then be changed by known methods to duplicate some or all of the active site amino acid residues of the phytase with the desired property. The modified phytase is then obtained by known methods (for example determining the DNA sequence, mutating the sequence to provide the desired amino acid sequence, and expressing the resulting protein), and is tested by assays for the desired property, e.g. specific activity, to confirm that the desired property is present.

In this context it should be mentioned that another possibility for producing phytases with improved properties is by isolating phytases from the same organism, like for example the Aspergillus ficuum, but different strains which can be found in nature and have been deposited by any of the known depository authorities. Their amino acid sequences can be determined by cloning their corresponding DNA sequences by methods as described, e.g. in European Patent Application No. (EP) 684 313. Once such sequences have been defined they can be modeled on the basis of the three-dimensional structure of the A. niger phytase and the active sites of both sequences can be compared to find out whether such phytase should have improved activity properties (see Example 8) or both active site sequences can be compared directly and than tested for increased and/or improved activity by the assays described in the present application.

It is furthermore an object of the present invention to provide a modified phytase which is obtainable by a process as described above.

It is in general an object of the present invention to provide a phytase which has been modified in a way that its activity property is more favorable than the one of the non-modified phytase, specifically such a phytase characterized therein that the amino acid sequence of the non-modified phytase has been changed by deletion, substitution and/or addition of one or more amino acids, more specifically such a phytase wherein changes have been made at at least one position which is homologous to one of the following positions of the amino acid sequence of the phytase of Aspergillus (A.) niger (see FIG. 1): 27, 66, 71, 103, 140, 141, 188, 205, 234, 235, 238, 274, 277, 282, 340 and/or 424, preferably 27, 66, 140, 205, 274, 277, 282 and/or 340, and even more specifically such a phytase which is the phytase of eukaryotic, preferably fungal, more preferably Aspergillus and most preferably Aspergillus fumigatus, origin.

It is furthermore an object of the present invention to provide such a phytase wherein at position 27 or at least at position 27 a change occurs, preferably a phytase wherein the amino acid at position 27 is replaced by one selected from one of the following groups:

a) Ala, Val, Leu, Ile; or

b) Thr or

c) Asn; and furthermore such a phytase wherein in addition to position 27 a change occurs also at position 66 or wherein in addition to position 27 a change occurs also at position 140 and/or at positions 274 and/or 277.

It is also an object of the present invention to provide a phytase as specified above which is characterized by at least one of the following mutations: Q27L, Q27N, Q27T, Q27I, Q27V, Q27A, Q27G, S66D, S140Y, D141G, A205E, Q274L, G277D, G277K, Y282H and/or N340S.

It is furthermore an object of the present invention to provide phytase muteins which are resistant against degradation by proteases of fungal, preferably Aspergillus and most preferably Aspergillus niger (ficuum) origin. Such muteins are characterized therein that at least at one of the following positions (which refers to the homologous position in the amino acid sequence of A. niger), namely position 130 or 129 and 130, preferably of the Aspergillus fumigatus or 167, 168 preferably of the A. nidulans phytase amino acid sequence, the amino acid which is present in the wild type sequence has been replaced against another amino acid which is known to change the protease sensitivity, e.g. in the case of A. fumigatus at position 130 from “S” to “N” and at position 129 from “R” to “L” and in case of A. nidulans at position 167 from “K” to “G” and at position 168 from R to Q. Such positions can be also combined with those providing for improved activity properties.

A desired property to be integrated into an unmodified phytase by sequence modification as described herein, may be a new property not present in the unmodified phytase, or may preferably be an existing property of the unmodified phytase which is to be improved, for example a specific activity over a broader pH range than in the unmodified phytase. The active site of the phytases is the part of the phytase which is the physical structure which provides all or part of the property. For example the binding site of the phytase provides the property of substrate specificity. Other parts of the phytase may have an influence on a given property, however the active site is the part which changes the property upon modification as described.

In this context a desired property which is to be improved, or an improved activity property means any type of improvement of the activity of the modified phytase as compared to the unmodified. This could mean for example a higher specific activity, preferably at least two fold or more preferably at least 3 to 4 fold higher in an assay known in the state of the art to measure phytase activity, see e.g. in EP 684 313 or described in the examples of the present application. Furthermore this could mean a different substrate specificity determined in an assay known in the state of the art or as described e.g. in the specific examples of the present invention. This could also mean a maximum of the specific activity at a different more favorable pH or a broad pH optimum (“improved pH profile”) determined by an assay as known in the state of the art or as described e.g. in the examples. This also could mean improved resistance to protease degradation, as described above. Finally this could also mean any combination of such properties.

“Homologous” in the context of the present invention means the best fit of the primary, preferably also secondary and most preferably also tertiary structure of the phytase to be modified and the phytase of Aspergillus niger. How such best fit can be obtained is described in detail in Example 1 of the present invention. FIG. 1 gives an example of such best fit for the phytase amino acid sequences of Aspergillus fumigatus and Aspergillus terreus aligned on the basis of the Aspergillus niger amino acid sequence which latter sequence is also used as the reference to which the positions of the other sequences, e.g. the ones named before, are referred to. Furthermore the modified Aspergillus fumigatus phytase with the Q27L mutation, means nothing else than the phytase of Aspergillus fumigatus wherein at position 27 according to the assignment as defined above (which is in fact position 23 of the Aspergillus fumigatus amino acid sequence) the naturally occurring glutamine (“Q” refers to the standard UPAC one letter amino acid code) has been replaced by leucine (“L”). All muteins of the present invention are designated in this way independent from whether they are protease resistant muteins or muteins with improved activity properties.

Constructing a polynucleotide comprising a DNA sequence coding for the modified phytase whose amino acid sequence was obtained as described above is performed by known methods such as those described below. The nucleotides coding for the active site which provides the desired property are changed so that at least one of the amino acids now encoded corresponds to an amino acid which is different in the active site of the unmodified phytase and the active site of the phytase which has the desired property. Integrating such a polynucleotide into vectors and host cells so as to express the modified phytase is also part of this invention and may be accomplished by known methods and as described below.

Thus it is furthermore an object of the present invention to provide a polynucleotide comprising a DNA sequence coding for a phytase as described above, a vector, preferably an expression vector, comprising such a polynucleotide, a host cell which has been transformed by such a polynucleotide or vector, a process for the preparation of a phytase of the present invention wherein the host cell as described before is cultured under suitable culture conditions and the phytase is isolated from such host cell or the culture medium by methods known in the art, and a food or feed composition comprising a phytase of the present invention.

In this context it should be noted that it is also an object of the present invention to provide a DNA sequence which codes for a phytase carrying at least one of the specific mutations of the present invention and which hybridizes under standard conditions with the DNA sequences of the specific modified phytases of the present invention or a DNA sequence which, because of the degeneracy of the genetic code does not hybridize but which codes for a polypeptide with exactly the same amino acid sequence as the one encoded by the DNA sequence to which it does not hybridize or a DNA sequence which is a fragment of such DNA sequences which maintains the activity properties of the polypeptide of which it is a fragment.

“Standard conditions” for hybridization mean in the context the conditions which are generally used by a person skilled in the art to detect specific hybridization signals and which are described, e.g. by Sambrook et al., “Molecular Cloning”, second edition, Cold Spring Harbor Laboratory Press 1989, New York, or preferably so called stringent hybridization and non-stringent washing conditions or more preferably so called stringent hybridization and stringent washing conditions a person skilled in the art is familiar with and which are described, e.g. in Sambrook et al. (s.a.).

It is furthermore an object of the present invention to provide a DNA sequence which can be obtained by the so called polymerase chain reaction method (“PCR”) by PCR primers designed on the basis of the specifically described DNA sequences of the present invention. It is understood that the so obtained DNA sequences code for phytases with at least the same mutation as the ones from which they are designed and show comparable activity properties.

The principles of the polymerase chain reaction (PCR) method are outlined e.g. by White et al., Trends in Genetics, 5, 185-189 (1989), whereas improved methods are described e.g. in Innis et al. [PCR Protocols: A guide to Methods and Applications, Academic Press, Inc. (1990)].

DNA sequences of the present invention can be constructed starting from genomic or cDNA sequences coding for phytases known in the state of the art [for sequence information see references mentioned above, e.g. EP 684 313 or sequence data bases, for example like Genbank (Intelligenetics, California, USA), European Bioinformatics Institute (Hinston Hall, Cambridge, GB), NBRF (Georgetown University, Medical Centre, Washington DC, USA) and Vecbase (University of Wisconsin, Biotechnology Centre, Madison, Wis., USA) or disclosed in the figures by methods of in vitro mutagenesis [see e.g. Sambrook et al., Molecular Cloning, Cold Spring Harbor Laboratory Press, New York]. A widely used strategy for such “site directed mutagenesis”, as originally outlined by Hurchinson and Edgell [J. Virol. 8, 181 (1971)], involves the annealing of a synthetic oligonucleotide carrying the desired nucleotide substitution to a target region of a single-stranded DNA sequence wherein the mutation should be introduced [for review see Smith, Annu. Rev. Genet. 19, 423 (1985) and for improved methods see references 2-6 in Stanssen et al., Nucl. Acid Res., 17, 4441-4454 (1989)]. Another possibility of mutating a given DNA sequence which is also preferred for the practice of the present invention is the mutagenesis by using the polymerase chain reaction (PCR). DNA as starting material can be isolated by methods known in the art and described e.g. in Sambrook et al. (Molecular Cloning) from the respective strains. For strain information see, e.g. EP 684 313 or any depository authority indicated below. Aspergillus niger [ATCC 9142], Myceliophthora thermophila [ATCC 48102], Talaromyces thermophilus [ATCC 20186] and Aspergillus fumigatus [ATCC 34625] have been redeposited on Mar. 14, 1997 according to the conditions of the Budapest Treaty at the American Type Culture Cell Collection under the following accession numbers: ATCC 74337, ATCC 74340, ATCC 74338 and ATCC 74339, respectively. It is however, understood that DNA encoding a phytase to be mutated in accordance with the present invention can also be prepared on the basis of a known DNA sequence, e.g. as shown in FIG. 6 in a synthetic manner and described e.g. in EP 747 483 by methods known in the art.

Once complete DNA sequences of the present invention have been obtained they can be integrated into vectors by methods known in the art and described e.g. in Sambrook et al. (s.a.) to overexpress the encoded polypeptide in appropriate host systems. However, a man skilled in the art knows that also the DNA sequences themselves can be used to transform the suitable host systems of the invention to get overexpression of the encoded polypeptide. Appropriate host systems are for example fungi, like Aspergilli, e.g. Aspergillus niger [ATCC 9142] or Aspergillus ficuum [NRRL 3135] or like Trichoderma, e.g. Trichoderma reesei or yeasts, like Saccharomyces, e.g. Saccharomyces cerevisiae or Pichia, like Pichia pastoris, or Hansenula polymorpha, e.g. H. polymorpha (DSM5215). A man skilled in the art knows that such microorganisms are available from depository authorities, e.g. the American Type Culture Collection (ATCC), the Centraalbureau voor Schimmelcultures (CBS) or the Deutsche Sammlung fair Mikroorganismen und Zellkulturen GmbH (DSM) or any other depository authority as listed in the Journal “Industrial Property” [(1991) 1, pages 29-40]. Bacteria which can be used are e.g. E. coli, Bacilli as, e.g. Bacillus subtilis or Streptomyces, e.g. Streptomyces lividans (see e.g. Anne and Mallaert in FEMS Microbiol. Letters 114, 121 (1993). E. coli, which could be used are E. coli K12 strains e.g. M15 [described as DZ 291 by Villarejo et al. in J. Bacteriol. 120, 466-474 (1974)], HB 101 [ATCC No. 33694] or E. coli SG13009 [Gottesman et al., J. Bacteriol. 148, 265-273 (1981)].

Vectors which can be used for expression in fungi are known in the art and described e.g. in EP 420 358, or by Cullen et al. [Bio/Technology 5, 369-376 (1987)] or Ward in Molecular Industrial Mycology, Systems and Applications for Filamentous Fungi, Marcel Dekker, New York (1991), Upshall et al.

Suitable vectors which can be used for expression in E. coli are mentioned, e.g. by Sambrook et al. [s.a.] or by Fiers et al. in Procd. 8th Int. Biotechnology Symposium” [Soc. Franc. de Microbiol., Paris (Durand et al., eds.), pp. 680-697 (1988)] or by Bujard et al. in Methods in Enzymology, eds. Wu and Grossmann, Academic Press, Inc. Vol. 155, 416-433 (1987) and Stüber et al. in Immunological Methods, eds. Lefkovits and Pernis, Academic Press, Inc., Vol. IV, 121-152 (1990). Vectors which could be used for expression in Bacilli are known in the art and described, e.g. in EP 405 370, Procd. Natl. Acad. Sci. USA 81, 439 (1984) by Yansura and Henner, Meth. Enzymol. 185, 199-228 (1990) or EP 207 459. Vectors which can be used for the expression in H. Polymorpha are known in the art and described, e.g. in Gellissen et al., Biotechnology 9, 291-295 (1991).

Either such vectors already carry regulatory elements, e.g. promotors, or the DNA sequences of the present invention can be engineered to contain such elements. Suitable promotor elements which can be used are known in the art and are, e.g. for Trichoderma reesei the cbh1- [Haarki et al., Biotechnology 7, 596-600 (1989)] or the pkil-promotor [Schindler et al., Gene 130, 271-275 (1993)], for Aspergillus oryzae the amy-promotor [Christensen et al., Abstr. 19th Lunteren Lectures on Molecular Genetics F23 (1987), Christensen et al., Biotechnology 6, 1419-1422 (1988), Tada et al., Mol.

Biotechnol. 17, 19-37 (1991)] and the pkiA-promotor [de Graaff et al., Curr. Genet. 22, 21-27 (1992)]. Suitable promotor elements which could be used for expression in yeast are known in the art and are, e.g. the pho5-promotor [Vogel et al., Mol. Cell. Biol., 2050-2057 (1989); Rudolf and Hinnen, Proc. Natl. Acad. Sci. 84, 1340-1344 (1987)] or the gap-promotor for expression in Saccharomyces cerevisiae and for Pichia pastoris, e.g. the aoxl-promotor [Koutz et al., Yeast 5, 167-177 (1989); Sreekrishna et al., J. Basic Microbiol. 28, 265-278 (1988)], or the FMD promoter [Hollenberg et al., EPA No. 0299108] or MOX-promotor [Ledeboer et al., Nucleic Acids Res. 13, 3063-3082 (1985)] for H. polymorpha.

Accordingly vectors comprising DNA sequences of the present invention, preferably for the expression of said DNA sequences in bacteria or a fungal or a yeast host and such transformed bacteria or fungal or yeast hosts are also an object of the present invention.

Once such DNA sequences have been expressed in an appropriate host cell in a suitable medium the encoded phytase can be isolated either from the medium in the case the phytase is secreted into the medium or from the host organism in case such phytase is present intracellularly by methods known in the art of protein purification or described, e.g. in EP 420 358 Known methods of protein purification may be used to isolate the phytases of this invention. For example various types of chromatography may be used individually or in combination. Gel purification may also be used. Accordingly a process for the preparation of a polypeptide of the present invention characterized in that transformed bacteria or a host cell as described above is cultured under suitable culture conditions and the polypeptide is recovered therefrom and a polypeptide when produced by such a process or a polypeptide encoded by a DNA sequence of the present invention are also an object of the present invention.

Phytases of the present invention can be also expressed in plants according to methods as described, e.g. by Pen et al. in Bio/Technology 11, 811-814 (1994) or in EP 449 375, preferably in seeds as described, e.g. in EP 449 376.

For example, a DNA sequence encoding a phytase of the present invention can be placed under the control of regulatory sequences from the gene encoding the 12S storage protein cruciferin from Brassica napus. The construct is thereafter subcloned into a binary vector such as pMOG23 (in E. coli K-12 strain DH5α, deposited at the Centraal Bureau voor Schimmelcultures, Baarn, The Netherlands under accession number CBS 102.90). This vector is introduced into Agrobacterium tumefaciens which contains a disarmed Ti plasmid. Bacterial cells containing this contruct are co-cultivated with tissues from tobacco or Brassica plants, and transformed plant cells are selected by nutrient media containing antibiotics and induced to regenerate into differentiated plants on such media. The resulting plants will produce seeds that contain and express the DNA contruct. Or the phytase-encoding DNA sequence can be placed under the control of regulatory sequences from the 35S promoter of Cauliflower Mosaic Virus (CaMV). The contruct is thereafter subcloned into a binary vector. This vector is then introduced into Agrobacterium tumefaciens which contains a disarmed Ti plasmid. Bacterial cells containing this construct are cocultivated with tissues from tobacco or Brassica plants, and transformed plant cells are selected by nutrient media containing antibiotics and induced to regenerate into differentiated plants on such media. The resulting plants contain and express the DNA construct constitutively.

The plant or plant part containing phytase can be used directly for the preparation of a feed composition or can be extracted from plants or plant organs by methods known in the art. Accordingly it is also an object of the present invention to provide a process for the production of the phytases of the present invention in plants or plant organs, like seeds, the phytases when produced by such methods, the transformed plants and plant organs, like seeds itself.

Once obtained the polypeptides of the present invention (which include modified phytases as described and active fragments thereof, and fusion proteins which include the phytases or fragments, or proteins which have stabilized by other moieties such as conjugation with polyalkylene glycols and such) can be characterized regarding their properties which make them useful in agriculture any assay known in the art and described e.g. by Simons et al. [Br. J. Nutr. 64, 525-540 (1990)], Schöner et al. [J. Anim. Physiol. a. Anim. Nutr. 66, 248-255 (1991)], Vogt [Arch. Geflügelk. 56, 93-98 (1992)], Jongbloed et al. [J. Anim. Sci., 70, 1159-1168 (1992)], Perney et al. [Poultry Sci. 72, 2106-2114 (1993)], Farrell et al., [J. Anim. Physiol. a. Anim. Nutr. 69, 278-283 (1993), Broz et al., [Br. Poultry Sci. 35, 273-280 (1994)] and Düngelhoef et al. [Animal Feed Sci. Technol. 49, 1-10 (1994)] can be used.

In general the polypeptides of the present invention can be used without being limited to a specific field of application for the conversion of inositol polyphosphates, like phytate to inositol and inorganic phosphate. For example phytases can be used to increase the nutrient value of plant material in animal feed by liberating from it inorganic phosphate which otherwise would otherwise not be accessible to non-ruminants. This reduces the amount of phosphorous which must be added to feed as a supplement and also reduces the amount of phosphorous which is excreted. Thus, phytases of this invention which have improved properties will enhance this process, or impart new benefits.

Furthermore the polypeptides of the present invention can be used in a process for the preparation of compound food or feeds wherein the components of such a composition are mixed with one or more polypeptides of the present invention. Accordingly compound food or feeds comprising one or more polypeptides of the present invention are also an object of the present invention. A person skilled in the art is familiar with their process of preparation. A phytase of this invention may be added to the complete feed preparation or to any component or premix or pelleted component. The effect of the added phytase may be an improvement in food utilization by virtue of the improved property or properties of the phytase. For example a phytase may have improved heat resistance to resist degradation caused by the food preparation process, and/or may have improved specific activity to liberate more phosphorous, and/or to liberate phosphorous in a wider range of conditions. Other properties of the modified phytase which increase the value or stability or other properties of the feed are also contemplated. Such compound foods or feeds can further comprise additives or components generally used for such purpose and known in the state of the art.

It is furthermore an object of the present invention to provide a process for the reduction of levels of phytate in animal manure characterized in that an animal is fed such a feed composition in an amount effective in converting phytate contained in the feedstuff to inositol and inorganic phosphate.

EXAMPLES Example 1 Homology Modeling of A. fumigatus and A. terreus cbs116.46 Phytase

The amino acid sequences of A. fumigatus [ATCC 13073] (see FIG. 1) and A. terreus cbs116.46 phytase (see FIG. 1) were compared with the sequence of A. niger (ficuum) phytase (see FIG. 1) for which the three-dimensional structure had been determined by X-ray crystallography. Crystallographic data are given in FIG. 8.

A multiple amino acid sequence alignment of A. niger (ficuum) phytase, A. fumigatus phytase and A. terreus cbs116.46 phytase was calculated with the program “PILEUP” (Prog. Menu for the Wisconsin Package, version 8, September 1994, Genetics Computer Group, 575 Science Drive, Madison Wis., USA 53711). The three-dimensional models of A. fumigatus phytase and A. terreus cbs116.46 phytase were built by using the structure of A. niger (ficuum) phytase as template and exchanging the amino acids of A. niger (ficuum) phytase according to the sequence alignment to amino acids of A. fumigatus and A. terreus cbs116.46 phytases, respectively. Model construction and energy optimization were performed by using the program Moloc (Gerber and Müller, 1995). C-alpha positions were kept fixed except for new insertions/deletions and in loop regions distant from the active site.

Only small differences of the modelled structures to the original crystal structure could be observed in external loops. Furthermore the different substrate molecules that mainly occur on the degradation pathway of phytic acid (myo-inositol-hexakisphosphate) by Pseudomonas sp. bacterium phytase and, as far as determined, by A. niger (ficuum) phytase (Cosgrove, 1980; FIG. 1) were constructed and forged into the active site cavity of each phytase structure. Each of these substrates was oriented in a hypothetical binding mode proposed for histidine acid phosphatases (Van Etten, 1982). The scissile phosphate group was oriented towards the catalytically essential His 59 to form the covalent phosphoenzyme intermediate. The oxygen of the substrate phosphoester bond which will be protonated by Asp 339 after cleavage was orientated towards the proton donor. Conformational relaxation of the remaining structural part of the substrates as well as the surrounding active site residues was performed by energy optimization with the program Moloc.

Based on the structure models the residues pointing into the active site cavity were identified. More than half (60%) of these positions were identical between these three phytases, whereas only few positions were not conserved (see FIG. 1). This observation could be extended to four additional phytase sequences (A. nidulans, A. terreus 9A1, Talaromyces thermophilus, Myceliophthora thermophila).

The results coming from sequence alignment and structural information including favourable enzyme-substrate interactions were combined to define the positions for mutational analysis which are shown in Table 1.

Example 2 Construction of Plasmids pUC18-AfumgDNA and pUC18-AfumcDNA

Plasmids pUC18-AfumgDNA and pUC18-AfumcDNA, the basic constructs for all the A. fumigatus muteins described below were constructed as follows.

pUC18-AfumgDNA: The genomic DNA sequence of the phytase gene of Aspergillus fumigatus was obtained by PCR using the “Expand™ High Fidelity PCR Kit” (Boehringer Mannheim, Mannheim, Germany) with primers #39 and #40 (designed on the basis of the genomic sequence shown in FIG. 6) and genomic DNA of Aspergillus fumigatus [ATCC 13073] from the A. fumigatus (NIH stock 5233) genomic library in a Lambda FixII vector [Stratagene, Lugolla, Calif. 92037, USA; catalog No. 946055].

Primer #39:

The reaction mix included 10 pmol of each primer and 200 ng of template DNA. 35 rounds of amplification were done with the following cycling values: 95° C., 1 min/56° C., 1 min/72° C., 90 sec. The PCR-amplified Aspergillus fumigatus mutein genes had a new BspHI site at the ATG start codon, introduced with primer #39, which resulted in the change of the second amino acid from a valine to an isoleucine. Furthermore, an EcoRV site was created with primer #40 downstream of the TGA termination codon of the gene.

The PCR fragment (approx. 1450 bp) was subsequently cloned into the Smal site of pUC18 using the “sure clone Kit” (Boehringer Mannheim s.a.) according to the supplier's recommendations. The resulting plasmid was named pUC18-AfumgDNA.

pUC18-AfumcDNA: This plasmid lacks the intron (small gap letters in FIG. 6) of the A. fumigatus phytase gene and was constructed as outlined in FIG. 13. Briefly, using primers Fum28 and Fum11 the 5′ end of exon 2 was amplified by PCR (see below), digested with NcoI and EagI (new restriction site introduced with primer Fum28) and ligated together with the linker coding for exon 1 made of primers Fum26 and Fum27 into the XbaI and NcoI sites of pUC18-AfumgDNA, thereby resulting in plasmid pUC18-AfumcDNA.

PCR reaction to get 5′ end of exon 2 of the A. fumigatus phytase:

  2 μl template: pUC18-AfumgDNA (20 ng)   1 μl dNTP's-mix (Boehringer Mannheim s.a.)   5 μl l0× Buffer   1 μl Taq polymerase (Boehringer Mannheim s.a.)  1.9 μl Fum11 (= 10 pmol)   2 μl Fum28 (= 10 pmol) 37,1 μl H₂O

In total 35 cycles with the temperature profile: 95° C. for 30 sec/56° C. for 30 sec/72° C. for 45 sec were made. The amplified fragment (approx. 330 bp) was extracted once with an equal volume of phenol/chloroform (1:1). To the recovered aqueous phase 0.1 volume of 3 M sodium acetate, pH 4.8 and 2.5 volumes of ethanol were added. The mixture was centrifuged for 10 min at 12000 g and the pellet resuspended in 20 μl of H₂O. Subsequently, the purified fragment was digested with NcoI and EagI and processed as outlined above.

Example 3 Construction of Muteins of the Phytase of Aspergillus fumigatus for Expression in A. niger

To construct all muteins for the expression in A. niger, plasmid pUC18-AfumgDNA was used as template for site-directed mutagenesis. Mutations were introduced using the “quick exchange site-directed mutagenesis kit” from Stratagene (La Jolla, Calif., USA) following the manufacturer's protocol and using the corresponding primers (FIG. 14). All mutations made are summarized in Table 1A and B wherein T1 to T7 and N1 to N6, respectively, refer to the muteins and “Mutation” to the amino acids replaced at such position. For example T5 refers to a mutein with a double mutation: L at position 27 for Q and L at position 274 for Q. The primer sets (A-H) used to introduce the corresponding mutations are shown in FIG. 14a. The newly introduced amino acid is shown in bold and the subscript indicates the position in the mature Aspergillus fumigatus enzyme concerning to the numbering of the A. niger amino acid sequence. FIGS. 15 and 16 outline the scheme for the construction of different plasmids pgT1-pgT7 and pgN1-pgN6 encoding the muteins carrying only one mutation (T1-T4; N1-N3) or more mutations (T5-T7; N4-N6). Clones harboring the desired mutations were identified by DNA sequence analysis as known in the art. The mutated phytases were verified by complete sequencing of the genes.

Example 4 Construction of Muteins of the Phytase of Aspergillus fumigatus for Expression in Saccharomyces cerevisiae

Construction of plasmids pcT1-pcT7 (FIG. 17a) and pcN1-pcN6 (FIG. 18), respectively, encoding the muteins T1-T7 and N1-N6 for the expression in S. cerevisiae was basically done as outlined in Example 3. Instead of using pUC18-AfumgDNA as the basic construct to introduce the mutations, plasmid pUC18-AfumeDNA was used (FIG. 13).

The plasmids pcDNA-N27, -G27, -V27, -A27, -127 and -T27 encoding the muteins N27, G27, V27, A27, I27 and T27 were constructed as follows:

A silent restriction site for AvrII was introduced into plasmid pcT1 by site directed mutagenesis as described in Example 3 using primer set I (FIG. 14a; FIG. 17b). The A. fumigatus phytase gene fragment AvrII/XhoI was then replaced by the linker fragment harbouring the desired mutations (FIG. 17c). Each linker fragment was generated by annealing of the respective pairs of synthesized polynucleotides (FIG. 14b; sense and antisense strand; 90 ng each) for 3 min at 70 ΓC in 9 μl distilled water.

Construction of plasmids pcT1-S66D and pcT1-S140Y-D141G encoding the A. fumigatus Q27L-S66D double mutant and the A. fumigatus Q27L-S140Y-141G triple mutant was basically carried out as described in Example 3. Plasmid pcT1, harbouring the mutation coding for Q27L, was used as template for site directed mutagenesis together with the corresponding primer sets J andK (FIG. 14a; FIG. 17b).

All mutations were verified by DNA sequence analysis of the entire gene.

Example 5 Expression in Aspergillus niger

The genes encoding the aforementioned A. fumigatus wild-type phytase and muteins (FIG. 16) were isolated with BspHI and EcoRV from plasmids pgDNAT1-pgDNAT7 and pgDNAN1-pgDNAN6 and ligated into the NcoI site downstream of the glucoamylase promoter of Aspergillus niger (glaA) and the EcoRV site upstream of the Aspergillus nidulans tryptophan C terminator (trpC) (Mullaney et al., 1985). The resulting expression plasmids had in addition the orotidine-5′-phosphate decarboxylase gene (pyr4) of Neurospora crassa as selection marker. FIG. 19 shows an example for such an expression plasmid carrying the gene encoding mutein T1 (van den Hondel et al., 1991). The basic expression plasmid described above corresponds basically to the pGLAC vector described in example 9 of EP 684 313. Transformation of Aspergillus niger and expression of the muteins was done as described in EP 684 313.

The supernatant was concentrated by way of ultrafiltration in Amicon 8400 cells (PM30 membranes) and ultrafree-15 centrifugal filter devices (Biomax-30K, Millipore).

The concentrate (typically 1.5-5 ml) was desalted in aliquots of 1.5 ml on a Fast Desalting HR 10/10 column (Pharmacia Biotech), with 10 mM sodium acetate, pH 5.0, serving as elution buffer. The desalted A. fumigatus samples were directly loaded onto a 1.7 ml Poros HS/M cation exchange chromatography column (PerSeptive Biosystems, Framingham, Mass., USA). A. terreus cbs116.46 [CBS 220.95] phytase was directly loaded onto a 1.7 ml Poros HQ/M anion exchange chromatography column. In both cases, phytase was eluted in pure form by way of a sodium chloride gradient.

Example 6 Expression in Saccharomyces cerevisiae

The intron less genes encoding the A. fumigatus wild-type phytase and the different muteins (FIGS. 17/18) mentioned above were isolated from the respective plasmids pUC18-AfumcDNA, pcDNAT1-pcDNAT7 and pcDNAN1-pcDNAN6 with EcoRI and EcoRV and subcloned either between the blunt ended XhoI and the EcoRI sites of plasmid pYES2 (Invitrogen, San Diego, Calif., USA) or the shortened GAPFL (glyceraldehyde-3-phosphate dehydrogenase) promoter and the PHO5 terminator as described by Janes et al. (1990). Transformation of Saccharomyces cerevisiae strains, e.g. INVSc1 (Invitrogen, San Diego, Calif., USA) was done according to Hinnen et al. (1978). Single colonies harbouring the phytase gene under the control of the GAPFL promoter were picked and cultivated in 5ml selection medium (SD -uracil) (Sherman et al., 1986) at 30Γ C under vigorous shaking (250 rpm) for 1 day. The preculture was then added to 500 ml YPD medium (Sherman et al., 1986) and cultivated under the same conditions. After four days cell broth was centrifuged (7000 rpm, GS3 rotor, 15 min. 5Γ C) and the supernatant was collected. Induction of the GALL promotor (plasmid pYES2 from Invitrogen, San Diego, Calif., USA) was done according to the manufacturers instructions. Purification of the muteins was as described in example 5 (s.a.).

Example 7 Determination of Phytase Activity and Substrate Specificity

Phytase activity was measured in an assay mixture containing 0.5% phytic acid (˜5 mM), 200 mM sodium acetate, pH 5.0. After 15 min incubation at 37° C., the reaction was stopped by addition of an equal volume of 15% trichloroacetic acid. The liberated phosphate ions were quantified by mixing 100 μl of the assay mixture with 900 μl H₂O and 1 ml of 0.6 M H₂SO₄, 2% ascorbic acid and 0.5% ammonium molybdate. Standard solutions of potassium phosphate were used as reference.

In case of pH optimum curves, purified enzymes were diluted in 10 mM sodium acetate, pH 5.0. Incubations were started by mixing aliquots of the diluted protein with an equal volume of 1% phytic acid (˜10 mM) in a series of different buffers: 0.4 M glycine/HCl, pH 2.5; 0.4 M acetate/NaOH, pH 3.0, 3.5, 4.0, 4.5, 5.0, 5.5; 0.4 M imidazole/HCl, pH 6.0, 6.5; 0.4 M Tris/HCl, pH 7.0, 7.5, 8.0, 8.5, 9.0. Control experiments showed that pH was only slightly affected by the mixing step. Incubations were performed for 15 min at 37° C. as described above.

For determination of the substrate specificities of wild-type and mutant A. fumigatus phytases, phytic acid in the assay mixture was replaced by 5 mM-concentrations of the respective phosphate compounds. The activity tests were performed as described above.

Protein concentrations were calculated from the OD at 280 nm, using theoretical absorption values calculated from the known protein sequences with the DNA* software (DNASTAR, Inc., Madison, Wis., USA). An absorption of 1.0 OD at 280 nm corresponds to 0.94 mg/ml A. fumigatus phytase and 0.85 mg/ml of A. terreus cbs116.46 phytase.

pH profiles of Aspergillus fumigatus mutants T1 (Q27L), T5 (Q27L, Q274L) and T6 (Q27L, Q274L, G277D) have drastically changed compared to the wild-type A. fumigatus phytase (see FIG. 2). All mutants showed equal pH profiles. Increase in specific activity at pH 5.0 of the muteins as compared to the wild-type phytase of Aspergillus fumigatus is shown in Table 2. Enzyme activities were measured under standard assay conditions at pH 5.0. Several individual measurements (n: number of assays) were averaged.

The pH profile of A. fumigatus phytase mutant Q27A resembles the pH profile of A. fumigatus wild-type phytase over nearly the whole pH range (FIG. 20). Whereas the specific activity of wild-type phytase is decreasing at pH values below pH 4.0, the specific activity of the phytase mutant Q27A remains nearly constant down to pH 2.9.

The single amino acid exchanges Q27L, Q27I, Q27V or Q27T have remarkably increased the specific activity over the whole pH range, especially between pH 5.0 and 7.5 (FIG. 20). Maximum values are reached at pH 6.5. In addition, mutation Q27T caused the highest specific activity values for phytic acid at low pH (pH 3.0-5.0).

Higher specific activities are also gained by the single mutations Q27G or Q27N, between pH 2.5 and 7.0, with maximum values at pH 6.0 (FIG. 20). The specific activity decreases at pH values below 3.5.

All single mutants still show a broad substrate specificity which is comparable to that of A. fumigatus wild-type phytase (FIG. 21). Some of the mutants show significantly higher specific activities than other mutants for selected substrates, e. g., the Q27T mutant for p-nitrophenyl phosphate and ATP, or the Q27G mutant for phosphoenolpyruvate.

As shown in FIG. 22 the combination of mutation Q27L with S66D or S140Y and D141G led to a shift of the pH profile towards lower pH. The maximum specific activity gained by the single mutation Q27L is further increased by the additional amino acid exchanges.

As shown in FIG. 3, Aspergillus fumigatus phytase mutant T1 (Q27L) showed no difference in substrate specificity compared to the triple mutant T6 (Q27L, Q274L, G277D).

The pH profiles of the muteins N1-6, except N2 show significant differences compared to the wild-type phytase (FIG. 10). Whereas the pH profile of mutein N4 is expanded towards lower pH, the profiles of muteins N3 to N6 are shifted towards lower pH. The muteins N5, N6 reach maximum activity already at pH 3.0.

The muteins N1 to N6 show in almost all cases a drastic reduction in specific activity for all tested substrates, except for phytic acid (FIG. 9). Specific activity for phytic acid remained unchanged compared to the wild-type phytase, whereas mutant N3 and N6 show a tendential higher activity (FIG. 19).

Example 8

As an alternative approach to obtain phytases with modified characteristics and to get a better idea about the natural variation found in phytase characteristics within a certain species, naturally occurring variants of A. fumigatus phytase were analysed. Phytase genes were obtained from six different isolates of A. fumigatus. The amino acid sequence of phytase from two of the A. fumigatus isolates (ATCC 26934 and ATCC 34625) showed no difference to the original amino acid sequence of wild-type A. fumigatus phytase ATCC 13073. Phytase from three other isolates had one or two amino acid substitutions, none of which directly affected the active site. Enzymatic characteristics remained unaffected by these substitutions (not shown). The phytase of isolate of A. fumigatus (ATCC 32239) differed in 13 positions in the signal sequence and 51 positions in the mature part of the protein compared to the original wild-type A. fumigatus phytase (ATCC 13073). Several of these substitutions affect variable amino acids of the active site cavity. This resulted in an increase in specific activity with phytic acid as substrate (47 U/mg, standard enzyme assay) and in loss of enzymatic activity above pH 7 (FIG. 24). Also in this case, the specific activity against phytic acid was increased relative to the specific activities with other substrates (FIG. 25).

Example 9

Construction of plasmids pc-S130N, pc-R129L-S130N, pc-K167G-R168Q encoding A. fumigatus [ATCC 13073] phytase S130N single mutant and R129L-S130N double mutant and A. nidulans phytase K167G-R168Q double mutant was basically carried out as described in Example 3. Plasmid pUC18-AfumcDNA was used as template for site directed mutagenesis together with the corresponding primer sets L, M and N (FIG. 14a; FIG. 26).

All mutations were verified by DNA sequence analysis of the entire gene.

Example 10

When expressed in A. niger and stored as concentrated culture supernatants at 4° C., the phytases from A. fumigatus, A. nidulans displayed tendency to undergo proteolytic degradation. N-terminal sequencing of fragments suggested that cleavage occured between amino acids S130-V131 and K167-R168 or R168-A169, respectively. Compared with 3D structure of A. niger phytase revealed that all cleavage sites are found within surface-exposed loop structures and are therefore accessible to proteases.

Site-directed mutagenesis at protease-sensitive sites of A. fumigatus phytase (S130N, R129L-S130N) andA. nidulans phytase (K167G-R168Q) yielded mutant proteins with considerably reduced susceptibility to proteolysis.

In contrast to expression in A. niger, proteolytic degradation was not observed when the phytases were expressed in Hansenula polymorpha.
